1. Insulation: Class-F/H
2. Producing procedure: Epoxy Resin Preimpregnated DMD is made by mylar and non-woven soft composite material immersed in class F resin.
3. Its temperature classification is F, high electrical and mechanical properties.
4. DMD epoxy preimpregnated material is widely used in insulation between layers of low voltage coil of dry type transformer and as the slot insulation and insulation between phases for F-grade motors.
